eusr v. Lnsrnomy l NE, PENNSYLVANIA.

Be it known that I, Gusr a citizen of the United' States, residing at Kane, in the county of McKean and VState of Pennsylvania, have invented certain new and useful 'Improvements in @casting-J umpers; and l do declare the following to be' av full, clear, and exact description of the invention, suchas will enable'others skilled in the art to which it appertainsto make and -use the same.

This invention relates to new and useful improvements inv coasting sleds, and more particularly to a coasting sled of that xtype which employ a single runner, and have a seat supported above the same, and theprimary object of the invention is to provide in a device of this character new and improved I vmeans for vertically adjusting theseat,1so

j Another object of this in vide in a device of this character, a coasting lsled having a runner 'with a flexible' adjustvable front end, so that the same is adapted for use over lumpy and rough roads.

A further object of the invention is to provide a device ofthis character which` is simple and durable in construction, `inexpen sive to manufacture, and one which will be `"With these and numerous other objects in view, my invention consists of the novel features of construction, combination and` arrangement of parts which will be herein referred to and more particularly pointed out in the specication and claims.

wooden runner 3, whichhas its forward end 4 formed with a longtitudinally extending slit 5 therem.` This longitudinally extending -slit 5 is for the purpose of giving an additional flexibility to the front end of the said runner for a purpose to lbe hereinafter more fully set forth. This wooden runner 3 has lits lower surfaceV covered withl a steel runner. or shoe 6, which has its opposite ends looped over the ends of the wooden runner as shown at 7 and 8. The loopedend 8 of the steel runner, which is the rear end of the same, has its extremity fiat against the upper surface of the said w)ooden' runner and is Secured thereto by a bolt or rivet 9, which extends through the same and also through a countersunk hole in the l wer surface ofthe which is either threadedly engaged therewith, or may be shrunk on the same, andthis clamp or collar 11 has projectingfoutwardly from opposite sides of the same at diametrically'opposite points, ears 12 and-13.

Connecting the ears 12 and thevrear end of the runners, and connecting a portion of" the ears 13 and the point adjacent the forward end of the wooden runner, .are'braces 14 and 15. These braces 14 and 15 comprise rods, which are securely fastened as clearly shown in Fig. 1, the'lower end of the brace f 14 being connected by Athe-rivet 9 'and the lower end of the brace 15 being connectedv to the wooden runner by abolt or rivet 16, which extends throughthe wooden runner 1 and also through .the countersunk aperture inthe steel runner 6. Tt will beV obvious that the upper ends of these braces are secured to the earsl 12 andV 13 by' pins extending transversely therethrough as' is clearly 13,'0'11 thev clamp jor collar 11, is pivotally connected a forwardly extending. rod 17 .which has its outer end screw threaded and is. adapted to receive thereon one end of a -turn buckle 18. The other end of-this adjacent j ioo turn buckle 18 is connectedwith the thread- ,110

ed end of the rod\19, which has its opposite .free end loosely mounted in the looped for- Award end 7 of the steel runner 6., This loose connection, which is clearly shown at 20, comprises .a transversely extending pin 2l projecting through an aperturein the 4iattened end of the rod 19, that projects finto the same, i the through an elongated opening 22, in the upper portion of said forward end 7. By this tance, so that this'sled is adapted for use ,on rough or lumpy roads.

Telescopingly engaging the hollow standard l, is an upper portion or section of the same which is-designated. by the numeral 23, and which comprises a rod adapted tojit said rod having mounted on its'upper end a seat 241, as clearly shown at V25. This seat 24 has diverging downwardlyand 'inwardly from the lower 'sur-C face, at opposite sides, rods-26 which con'- nect the vsaine with a clamp 27 slidably mounted on the. outer surfaceof the standard l., ATlns clamp -27 is provided with ears 28, which are adapted to engage the lower purpose of which'is obvious.

sled very strong anddurable, yet keep the obvious that I have provided -in this coasting This invention also embodies certaln structural details, that make this' same very light so' that it may be carried with very -little effort.

From the foregoing description, the construction of my improved coasting sledor jumper, the manner of applying the same to use and the operation thereof, will be readily understood and it will be seen that I have provided a simple, inexpensive and efiicient means forv carrying out the objects of the invention;

l I claim:

1. A coasting sled comprising a runner norm-ally straight from end. to end and adapted to haveits front end flexed, a standard rising from the runner and supporting a seat, and an adjustable connection extending downwardly` and forwardly from the upper end of the standard to the front end of the runner, whereby said end of the runner may be flexed.

.2. A coasting sled comprising a runner, a lstandard supporting a seat on its upper end rising therefrom, a collar on said standard, a rod extending from the same, an ad- 'ditional rod loosely connected with the front end of said runner, and a turn buckle adjustably securing the free endsl of the said rods.

3. A coasting sledl comiplrising a wooden runner having a flexible ont end, a s teel runner thereon having looped ends overlap- 'ping the opposite ends of said wooden runner, a standard supporting a seat on its upper end rising from the Wooden runner, a

collar on said standard, brace rods connecting said collar and runner, a rod projecting forwardly from said collar, a rod pivotally connected at one end with` theI forward looped end of the steel runner and,

the free ends .of said rods adjustably connected by a .turn buckle. l

4. A coasting, sled comprising a wooden runner having its front end slit longitudinally between its upper and lower faces, a metal runner thereon having a looped front endv overlapping said front end of the wooden runner and supporting a seat, and

a 'longitudinally adjustable connection be tween the standard and looped vend of the metal runner whereby the front ends of the runners I nay be flexed..

, In testimony whereof I have hereunto set my hand in presence'of two subscribing witnesses.'
